Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White

40 ms ... rise ↗ and fall ↘ combined

↗ 21.2 ms rise

↘ 18.8 ms fall

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 96 % of all devices are better.This means that the measured response time is worse than the average of all tested devices (25.6 ms).

↔ Response Time 50% Grey to 80% Grey

43.2 ms ... rise ↗ and fall ↘ combined

↗ 25.2 ms rise

↘ 18 ms fall

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 61 % of all devices are better.This means that the measured response time is similar to the average of all tested devices (41 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM detected

21740 Hz

≤ 99 % brightness setting

The display backlight flickers at 21740 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 21740 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9247 (minimum: 43 - maximum: 142900) Hz was measured.
